Hi Mika, Thank you for your email. On 28-10-2024 09:18, Mika Westerberg wrote:
I still see similar issue even with the v6.9 kernel. The link goes up an down unexpectly. I wonder if you could try to take traces of the control channel traffic? I suggest to use v6.11 kernel because it should have all the tracing bits added then install tbtools [1] and follow the steps here: https://github.com/intel/tbtools?tab=readme-ov-file#tracing Then provide both full dmesg and the trace output. That hopefully shows if some of the access we are doing in the Linux side is causing the link to to drop. Let me know if you need more detailed instructions. Also please drop the "thunderbolt.host_reset=0" from the command line as that did not help, so it is not needed.
Dropped thank you.
